Detailed Description

Subclass of value for objects: a collection of key/value pairs
preserving the ordering in which keys were inserted.

Preserving the order eliminates non-determinism in the output,
making it easier for the user to compare repeated invocations.

static

Subroutine of json::compare for comparing a pairs of objects.

Referenced by json::value::compare().

compare() [2/2]

int value::compare ( const json::value & val_a, const json::value & val_b )

staticinherited

A deterministic total ordering for comparing json values, so that we
can e.g. put them in std::map.

This is intended to follow the condition for equality described in
the JSON Schema standard (§4.3, “Instance equality”), as referenced
by SARIF v2.1.0 (§3.7.3 "Array properties with unique values"), but has
the following limitations:
- numbers are supposed to be checked for "the same mathematical value",
but in this implementation int vs float numbers won't compare as equal,
and float number comparison is bitwise
- strings are supposed to be "the same codepoint-for-codepoint", but
this implementation doesn't take into account canonicalization issues.

dump() [1/2]

void value::dump ( ) const

inherited

A convenience function for debugging.
Dump to stderr with formatting, and a trailing newline.  

References dump().

dump() [2/2]

void value::dump ( FILE * outf, bool formatted ) const

in which the keys were originally inserted.
